OLDSMOBILE DELTA 88 ENGINE PROBLEM

GM designers put them all over depending on which engine you have. Follow the belts to the pump. Ignore the lowest pulley in the middle of the engine. Of the rest of them the power steering pump pulley will be the largest in diameter. The cap will be about two inches in diameter. Turn it 1/4 turn counter-clockwise, then lift it up. It will have a dipstick in the middle to show the fluid level.
